Crash when KIF begins running.

[kyleplattner]

Has anyone run into this: 

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[KIFTestStep countByEnumeratingWithState:objects:count:]: unrecognized selector sent to instance 0xe6ad1a0'

when startTestingWithCompletionBlock is called?

I haven't seen that, but it looks like you have a KIF step in memory where you're expecting an array or other enumerable collection. I would suggest using a combination of exception break points and malloc stack logging or Instruments to try and find the culprit.
